COMBINED SCREEN AND STORM DOOR.

SPECIFICATION forming part of Letters Patent No. 736,802, dated August18, 1903.

Application filed December 11, 1902. Serial No. 184,810. (No model.)

T0 on whom it may concern:

Be it known that I, LUITJEN J. R. DE VRIES, a citizen of the UnitedStates, residing at Panola, in the county of Woodford and State ofIllinois, have invented certain new and usev ful Improvements in aCombined Screen and Storm Door; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention is an improved combined screen and storm door; and itconsists in the peculiar construction and combination of deviceshereinafter fully described and claimed.

The object of my invention is to provide an improved door which isadapted for use both as a screen-door in warm weather and as astorm-door in cold weather.

In the accompanying drawings, Figure 1 is an exterior elevation of acombined screen and storm door embodying my improvements with partsremoved to disclose subjacent constructions. Fig. 2 is a detailtransverse sectional view of the same, taken on the plane indicated bythe line a a of Fig. 1. Fig. 3 is a similar view taken on the planeindicated by the line b b of Fig. l, and Fig. 4 is a detail perspectiveview of one of the springcatches.

In the embodiment of my invention here shown the screen 1 is provided inits outer side with rabbets 2 in the inner corners or angles of its sidebars 3 and top, bottom, and center cross-bars 4, 5, and 6. These rabbetsare right angular in cross-section, and in the lower sides thereof areformed outwardlyprojecting beads or flanges 7. The screen fabric 8 hasits edges placed'on the bottom of the said rabbets. The beads or flanges7 are preferably triangular in cross-section and have outwardlyconverging sides. The stretcher-bars 9 are placed in the rabbets 2 andbear on the outer side of the edge portions of the screen fabric. Thesestretcher-bars are provided on their inner sides with grooves 10,whichare adapted to receive the beads or flanges 7 of the door-frame and tosnugly fit the same. Owing to the shape of the said beads or flanges andthe said rabbets, the screen fabric is stretched across the door, aswill be understood. The thickness of the stretcher-bars 9 exceeds thedepth of the rab- 'Fig. 2.

When it is desired to convert the screendoor into a storm-door, I employa covering fabric 11, which may be made of oil-cloth'or other suitablematerial and which is of sufficient size. This covering fabric is placedon the door 1 so that its edges project beyond the stretcher-bars 9. Inpractice the width and length of the'covering fabric 11 is such that theedges thereof project about a halfinch beyond the outer sides of thestretcherbars 9. Around the said stretcher-bars and upon the projectingedge portions of the covering fabric is placed a stretcher-frame 12. Thesame is here shown as comprising a pair of side rods 18 14, an uppercross-rod 15, and

a lower cross-rod 16. The latter and the rod 15 are pivotally jointed tothe upper and lower ends of the side rod 13. The upper end of the siderod 14 is pivotally jointed to one end of the rod 15, and the lower endof the rod 14 is slidably engaged with an eye 17, with which one end ofthe lower cross-rod 16 is provided. The construction of thestretcherframe enables the same to be very compactlyn disposed when notin use, as will be understood.

- t On the outer side of the door 1 are a number of pivotally-mountedcatches 18, which are adapted to engage the stretcher-frame to securethe latter to the door, and hence cause the stretchecframe to coact withthe stretcherbars 9 to stretch the outer or cover fabric 11 andsecnre'the same firmly on the outer'side of the door, and yet in suchmanner that it may be readily detached therefrom. Each of these catchescomprises a spring base portion or arm 19, which is normally curvedlongitudinally from end to end, as shown in Fig. 4, and a lug 20, whichprojects outwardly from one end of the spring brace or arm and has onits inner side a projecting hook or shoulder 21, adapted to engage thestretcherframe. This shoulder or hook 21 has on its 10o under side abevel 22, forminga rentrant angle or notch to receive thestretcher-frame and lock: the catch 18 to the said stretcherframe andprevent accidental disengagement of the catch therefrom. The pivots 23of the said catches are here shown as ordinary screws. In practice thesame may be nails or other suitable devices, and I do not limit myselfin this particular. It will be understood that the spring bases or arms19 of the catches bear upon the outer side of the doorframe and thatowing to the resiliency of the said spring-bases the same coact with thenotches 22 to keep the hooks or shoulders of the said catches inengagement with the stretcher-frame.

In order to further strengthen the connection between the outer orcovering fabric and the door frame, I provide a transverse stretcher-rod24, which is disposed across the outer or covering fabric at or near thecentral portion thereof, bears thereagainst to press the same on theouter sides of the stretcher-bars 9 to prevent the said outer orcovering fabric from flapping, and the ends of the said stretcher-rodare provided with hooks 25, which are engaged by the stretcherframe 12and pass .under the same, as shown in Fig. 2. Hence the stretcher-frame,which is itself secured on the outer side of the door by thespring-catches, serves to secure the transverse stretcher-rod, and thelatter coacts with the stretcher-bars 9 to strengthen the connectionbetween the outer or covering fabric and the door.

It will be understood that by reason of the stretcher-bars 9, whichproject beyond the outer side of the door, and the stretcher-frame,which bears on the outer side of the outer or covering fabric andextends around the outer sides of the projecting portions of saidstretcher-bars, the outer or covering fabric is so tightly stretched onthe door that the same is prevented from flapping to such an extent asto cause it to come in contact with the screen fabric, and hence wear ofboth the outer and covering fabric and the screen fab- ,ric isprevented.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of my invention will be readily apparent, it is thought,without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. A door having rabbets in its outer side extending around the same, incombination with a screen fabric having its edges disposed in thebottoms of said rabbets, stretcher-bars in said rabbets and projectingbeyond the outer side ofthe door, an outer fabric on said stretcher-barsand projecting outwardly beyond the same, and a stretcher-frame fittedon and around the said stretcher-bars and hearing against the outer sideof the said outer or covering fabric ,to secure the latter on saidstretcher-bars, substantially as described.

2. In combination with a door having stretcher-bars projecting from oneside thereof and extending around the same, a covering fabric bearing onand extending beyond the outer sides of said stretcher-bars, astretcherframe engaging the projecting edges of said covering fabric andfitting around the outer sides of said stretcher-bars, and means todetachably secure said stretcher-frame to the door, substantially asdescribed.
